在vxWorks中怎么为一个物理网口绑定多个IP地址

也可以叫共用一个IP吧。。我想

cat "/etc/modules.conf" 中加上

alias bond0 bonding

options bond0 miimon=100 mode=0

其中mode=0为负载平衡,

mode=1为备份时。。我试过把网线拨掉一根也完全正常。。因为另外一台一直在ping

[root@shlinux root]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

IPADDR=192.168.7.112

[root@shlinux root]# cat /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

ONBOOT=yes

IPADDR=192.168.7.112

[root@shlinux root]# cat /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

BOOTPROTO=static

IPADDR=192.168.7.112

NETMASK=255.255.255.0

NETWORK=192.168.7.0

BROADCAST=192.168.7.255

ONBOOT=yes

在"/etc/rc.d/rc.local"中加如下两句

ifenslave bond0 eth0 eth1

service network restart别忘了这句，否则eth1就会启动不了，兄弟们可能会发现在启动的时候会有eth1失败的提示，不过有了这句之後会发现後OK了。

取决于你的程序怎么写的，默认会每次启动用缺省的配置（头文件里的定义）覆盖RAM上的数据，具体地址要看你头文件里的定义。通常应该判断启动模式，如果是冷启动才会执行上述的覆盖 *** 作，否则使用RAM中的配置。

具体文件名应该是config.h, 不过启动模式的分支需要要你自己来加。

不清楚你的实际文件/情况，仅以问题中的样例/说明为据；以下代码复制粘贴到记事本，另存为xx.bat，编码选ANSI
